I’m not liking the ‘new’ use of udev rules to set network interfaces. It makes creating templates a tad more annoying.
I’m also not a fan of the use of NetworkManager in RHEL, but I didn’t install it, so I guess that doesn’t count.
Anyway, for those who wish to build VM templates remember this:
Do this just before you shutdown and convert to template and it will detect the new NIC’s on boot.
